Avro 557 Ava

Avro · United Kingdom · first flew 1924 · bomber

The Avro 557 Ava was a large twin-engine British torpedo bomber biplane designed in the early 1920s to meet a Fleet Air Arm requirement for a carrier-capable anti-shipping aircraft. Its substantial size and twin-engine layout distinguished it from contemporary single-engine torpedo carriers.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Very large biplane with twin engines mounted between the wings, prominent twin tail fins, and a wide fuselage designed to carry a torpedo externally; the 29.5 m wingspan is exceptional for a British torpedo aircraft of the period.

History

Built to an Air Ministry specification for a twin-engine torpedo bomber, the Avro 557 first flew in 1924 but was not selected for production, losing out to smaller, more practical single-engine designs. Only two prototypes were completed.

Variants

Two prototypes were built with minor differences; no production order followed.

Where you'll see it

Evaluated by the Fleet Air Arm but not adopted for service; the Ava remained a prototype throughout.
